LAMP-CHIMNEY ATTACHMENT FOR MEDICAL VAPORIZING AND HEATINS PURPOSES.

SPECIFICATION forming part of Letters Patent No. 491,827, dated February14, 1893.

Application filed May 9. 1892. Serial No. 432.349. (No model.)

To aZZ whom it may concern;

Be it known that I, JOSEPH E. WENMAN, of East Liverpool,in the county ofOolumbiana, and State of Ohio, have invented a new and usefulImprovement in Lamp-Chimney Attachments for Medical Vaporizing andHeating Purposes, of which the following is a full, clear, and exactdescription.

This invention consists in a perforated metal tube and attached capdevicedesigned to rest upon an ordinary glass lamp chimney for medicalvaporizing and heating purposes, substantially as hereinafter describedand more particularly pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 represents a view in elevation of a glass lamp chimney in part,with my improved attachment or device applied, and showing, by dottedlines, a retort seated thereon or in with attached tube for medicalvaporizing purposes; Fig. 2, a vertical sectional view of the same uponthe line 2-2 in Fig. 8, looking in direction of the arrow at; Fig. 3, atop or plan View; and Fig. 4, a horizontal section upon the line 4-4 inFig. 2.

A is a metal tube having two rows of perforationsfarranged one above theother in its sides, said tube being of a little larger diameter than thetop of the glass lamp chimney B upon which it rests. O is a downwardlyflaring cap attached to said tube at or near its top and surrounding thetube. This cap, which may be called a cooling cap, serv es to protectthe rubber inhaling or vaporizing tube 1) of a medical vaporizing retortD carried by the tubeAfrom beingburned should said flexible or rubbertube come in contact with the metal tube A. Said cap also prevents theheated air and gases passing up the lamp chimney into the tube A fromtoo freely escaping through the upper rows of perforations 0 in saidtube, yet not interfering with the necessary ventilation or free passageof outside air. In fine, the cap 0 keeps the heat in the tube A so thatthe retort or vessel seated on or in said tube will be heated quickerthan without such cap.

The metal tube A that rests by means of internal projections or hooks clupon the glass lamp chimney, has two rows of side perforations 0, 0',one row above the other to admit of an adequate supply of air,-so thatalmost any lamp can be used for heating purposes which the tube A,virtually forming an extension of the lamp chimney, is designed for. Inaddition to the internal projections or rests d, said tube A is furtherprovided with an upper series of internal vprojections or rests 01 abovethe rows of apertures c. This upper series of projections 01' isintended to support or carry the retort D which is made of fireproofmaterial, such, for instance, as porcelain or granite, and is intendedto vaporize medical liquids for the treatment or cure of throat and lungailments, the Vapor being conveyed or directed as required by theflexible tube b. The projections cl d are formed by punching thematerial of the tube A inwardly and thus the apertures c c aresimultaneously formed. There is also a series of lateral projections 01extending outward from the top of the chimney extension or tube A. Theseprojections will serve as rests for larger vessels for general orspecial heating purposes, when the chimney extension is not used forgenerating vapor in a medical retort as stated.

Having thus fully described my invention, I claim as new, and desire tosecure by Letters Patent 1. A lamp chimney attachment, comprising anopen ended tube A having an upper and lower series of projections (1 clpunched from its outer side inwardly and the series of apertures formedby the removal of the material forming the said projections,substantially as set forth.

2. A lamp'chimney attachment, comprising an open ended tube having upperand lower apertures, upper and lower internal projections and theexternal depending conical cap C secured at its contracted end to theupper supporting projections cl (1', upper outer sup- 1o edge of thesaid tube, substantially as set ports or projections d and a downwardlyforth. flaring cap 0, essentially as and for the pur- 3.
